High heat this weekend, what not to leave in your car

High temperatures Thursday got up to 86 degrees in Alpena, 82 degrees in Saginaw and 90 degrees in Minneapolis. That heat over Minnesota will be heading in our direction over the weekend. It’s going to feel increasingly sticky Saturday and Sunday.

A line of showers extends from the eastern Upper Peninsula to around the Traverse City area and into central Wisconsin. As this line of showers continues to progress toward to the southeast, it’s running into drier air. That will cause these showers to dry up as they approach Northeast Michigan. Overall, partly cloudy skies are in the forecast tonight. Clear skies over Minnesota and the Dakotas will settle over northern Michigan this weekend.

Temperatures will heat up to about 90 degrees Saturday, then lower 90s Sunday. When the outdoor temperature is 90 degrees, after the air conditioning is turned off, the inside of a car will rise to 109 degrees in just 10 minutes, then 119 degrees at the 20-minute mark. The high heat makes it dangerous to leave kids or pets in the car.

Friday: Partly cloudy, except possibly a spotty shower in the afternoon. Predawn lows will head down close to 55 degrees. Late-morning temperatures will rise to around 70 degrees. Afternoon highs will reach near 80 degrees. Evening temperatures will cool from the middle 70s to middle 60s.

Saturday: Partly cloudy and hot. Early-morning temperatures will begin around 62 degrees. Temperatures will already feel warm by the late-morning, close to 80 degrees. Afternoon highs will heat up to about 90 degrees. It will continue to feel very warm in the evening with temperatures heading from the middle 80s to middle 70s.

Sunday: Sunny and sticky. Early-morning lows will be near 65 degrees. It will begin to feel sticky as temperatures reach the 80s in the late-morning. Afternoon highs will get close to 92 degrees, that’s going to be about 20 degrees above “normal!” Evening temperatures will be in the 80s to upper 70s.
